Kim Kardashian and Kanye West's daughter North West is only six months, but already her eyebrows have sparked envy.

After Kardashian posted a photo Monday on Instagram of her smiling daughter, her fans openly speculated whether Kardashian was already having her child's eyebrows groomed.

"Eyebrows done already?" one commentor wrote beneath the photo.

"I've never seen a baby with arched even eyebrows. Her unibrow was cute, why get rid of it?" another fan commented.

At first, Kardashian laughed off the speculation.

"Do people really think I would wax my daughters eyebrows so young? Come on, I'd wait until she's at least 2 1/2!" she tweeted Tuesday.

Then, more serious, she wrote, "I'm kidding!!! Its pretty sick for people to insinuate that I would wax my daughters eyebrows. They are thick, natural and amazing!"
